AUTOMATIC OILING DEVICE.

SPECIFICATION forming part of Letters Patent No. 422,284, dated February25, 1890.

Application filed August 15, 1889- To all whom, it may concern.-

Be it known that we, ELWIN BENNER and WVILLIAM B. AYRES, both residentsof Phillipsburg, in the county of Deer Lodge and Territory of Montana,have invented certain new and useful Improvements in Automatic OilingDevices; and we do hereby declare that the following is a full, clear,and eXact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

Our invention relates to improvements in automatic oiling devices, andhas especial refence to a device for automaticallylubricating such partsof machinery or engines as the crank-pins and cross-heads; and theobject of the invention is the production of an inexpensive device whichwill supply the lubricant in the desired quantity to the parts of themachine. V

The invention consists of a stationary oilfeeding device and a devicecarried by the movable part of the machine for receiving and deliveringthe oil to the part to be lubricated.

The invention also consists in the novel construction, combination,arrangement, and adaptation of the parts comprising the oiler,all asshown, described, and specifically claimed.

In the accompanying drawings,forming part of this specification, and inwhich like letters of reference indicate corresponding parts, Figure 1represents a side elevation, partly in section, of an automatic oilerembodying our invention in position for use; and Fig. 2 represents aside elevation of a steam-engine with our improved oiler in positionthereon for lubricating the desired parts of the same. Fig. 3 representsa side elevation of an automatic oiler upon an enlarged scale.

Referring by letter to said drawings, A designates a cup for containingthe oil or lubricant, to the lower portion of which is secured thesleeve B, having sight-openings, and to said sleeve is secured thesupply or feed pipe C, which is bent as shown, and is provided with afeed opening or outlet D. Below said outlet D is the porous conductor E,made of manila or other suitable material, which will Serial No.320,832| (No model.)

conduct oil, and said conductor is placed in a cup F, from which leadsthe pipe G for conveying the oil to the part of the machinery to beoiled, which, in this instance, is the wristpin of an engine.

The device is supported on a stand H of suitable construction.

From the foregoing description, taken in connection with the drawings,the operation of our device will be readily understood, and is asfollows: The stationary cup is filled with oil, which passes from thencein limited quantity to the feed-opening of the pipe,'and the movable cupcarrying the porous conductor causes said conductor to move near thefeedopening and take a certain amount of the oil, and thus feed the sameby means of the conductor to the desired part of the machinery, and thuskeep the sam e lubricated at all times.

It will thus be seen that we provide a device which automaticallysupplies the oil to the machinery, and which will supply only enough toinsure proper lubrication and avoid Wasting the oil.

The advantages of our device will be readily understood and appreciatedby all skilled in the art.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

The herein-described oiling device, consisting of the standard carryingthe horizontal support, the U -shaped pipe secured at its ends to thehorizontal support and having a feedopening, the oil-cup communicatingwith said pipe, and the cup having porous material to receive the oil,said cup being attached to a movable part of the machinery,substantially as described.

In testimony that we claim the foregoing as our own we have hereuntoaffixed our signatures in presence of two witnesses.
